Effects of planes of weakness on uniaxial compressive strength of model mine pillars
Uniaxial compressive strength of model rock pillars was studied as function of angle and spacing of noncohesive planes of weakness; model pillars were prepared from NX 2-1/8 in. diam drill core of limestone, sandstone, and granite, and planes of weakness were diamond saw cuts ground flat and smooth; 400 model pillars were tested in uniaxial compression; results indicate that uniaxial compressive strength of model pillars decreases rapidly as angle of plane of weakness increases from 30 to 57°, and that spacing of these planes of weakness has only minor effect on strength.
